Where Do I Even Start?

Brenae • TJLx2💋
I'm 24 years old, 5'2 & 160 pounds. I want to lose 20 pounds but idk where to start. I was thinking about buying some weight lost pills but I don't really trust those things. I already have a waist trainer but I never wear it. I'm a manger at a restaurant so I work 50+ hours weekly, no time for gym. Idk what to do, i need help. I can never follow thru on anything. HELP, ADVICE Please!!!!!
